Everything in game looks good until I kill something and then it turns bright green or black including skeletons. Antone ever get this or know what I should be looking at to fix it?

Are you playing with MMM (particularly older versions)? If so, I believe this can occur if the BSA was not renamed properly.

What elizb said, except it's the latest MMM release that comes with a bsa. So if running http://www.gamesas.com/index.php?/topic/1116296-relz-martsmonstermod37b3-public-release-3-relz/, make sure that you have the bsa and, if so, that it is renamed correctly. If running an earlier version, check that all resources are installed - or better yet, update to 3.7b3PR3, but note that you have to remove any previous MMM resources before doing so.

Definitely have the latest version of MMM, 3.7b3p3, and everything was working fine after I set up FCOM. Problem started after I added some other mods. Does not happen if I do not have MMM Extra Wounding active. So one of the mods I added and Extra Wounding appear to not be getting along. Will have to deactivate one by one and see which it is.
